Polypeptides having endoglucanase activity and polynucleotides encoding same

An isolated polynucleotide encoding a polypeptide having endoglucanase activity, selected from the group consisting of:

• (a) a polynucleotide encoding a polypeptide comprising an amino acid sequence having at least 90% sequence identity with the mature polypeptide of SEQ ID NO:
• 2;
• (b) a polynucleotide encoding a polypeptide which hybridizes under at least high stringency conditions with (i) the mature polypeptide coding sequence of SEQ ID NO:
• 1, (ii) the genomic DNA sequence of the mature polypeptide coding sequence of SEQ ID NO:
• 1, or (iii) the full-length complementary strand of (i) or (ii), wherein high stringency conditions are defined as prehybridization and hybridization at 42° C. in 5×SSPE, 0.3% SDS, 200 μg/ml sheared and denatured salmon sperm DNA, and 50% formamide and washing three times each for 15 minutes using 2×SSC, 0.2% SDS at 65° C.;
• and
• (c) a polynucleotide encoding a polypeptide comprising a nucleotide sequence having at least 90% sequence identity with the mature polypeptide coding sequence of SEQ ID NO:
• 1.
